We evaluated a portable blood gas analyzer for its speed, reliability, and usefulness during interhospital transportation of critically ill children in a prospective study. The accuracy of a portable blood gas analyzer (PBGA) was first established by comparing its results with values obtained from a standard blood gas analyzer. The speed, accuracy, and usefulness of the PBGA were then compared with those of standard analyzers at 10 referring hospitals during interhospital transportation of critically ill children. A highly significant linear correlation was demonstrated between values obtained using the PBGA and those derived from standard analyzers. The time required to obtain blood gas results was 2 min with the portable device, significantly less than the mean of 8.4 min +/- 6.4 min (range 1-24 min) required to get results from the laboratory facilities of the referring hospitals. Modification of treatment or adjustment to mechanical ventilation was required in 30% of transported patients based on blood gas results obtained immediately before departure from the referring hospital. We conclude that a portable blood gas analyzer provides rapid, reliable, and useful data that help to determine therapy for critically ill children awaiting interhospital transport.
在一项前瞻性研究中，我们评估了一种便携式血气分析仪在危重症儿童院际转运过程中的速度、可靠性和实用性。首先，通过将便携式血气分析仪（PBGA）的结果与标准血气分析仪获得的值进行比较，确定了其准确性。然后，在10家转诊医院对危重症儿童进行院际转运期间，将PBGA的速度、准确性和实用性与标准分析仪进行了比较。使用PBGA获得的值与标准分析仪得出的值之间显示出高度显著的线性相关性。使用便携式设备获取血气结果所需的时间为2分钟，明显少于从转诊医院实验室设施获得结果所需的平均8.4分钟±6.4分钟（范围为1 - 24分钟）。根据转诊医院出发前立即获得的血气结果，30%的转运患者需要调整治疗或机械通气。我们得出结论，便携式血气分析仪可提供快速、可靠且有用的数据，有助于为等待院际转运的危重症儿童确定治疗方案。
